Range of Motion

Definition

Range of motion refers to the full movement potential of a joint, usually its range of flexion and extension.

Scientific / Technical Definition

Range of motion (ROM) is the degree of movement that occurs at a specific joint. This movement depends on the structure of the joint, the flexibility of the tissues surrounding the joint, and muscle function. It is typically measured in degrees using a goniometer and is used to assess and monitor joint health and function.

Benefits

• Improves flexibility and joint function.
• Enhances performance in physical activities.
• Helps prevent injuries related to joint and muscle stiffness.
• Aids in maintaining mobility with aging.

Examples

• The range of motion in the knee during a squat.
• The shoulder's range of motion when lifting the arm overhead.
• The hip's range of motion during a leg lift.

Additional Information

• Importance: Maintaining an appropriate range of motion in your joints is crucial for overall body mechanics, coordination, and balance. It is particularly important for athletes and elderly individuals to sustain functional range of motion to enhance performance and activities of daily living.
